BOILER PITCH: The Frontier pressure vessel is manufactured with the rear ½ to 1 bubble higher to allow for proper air
removal. This pitch is carefully set at the factory when the boiler is built. Be sure to level the stand prior to mounting the
boiler on the stand. When the stand is level, the pitch is correct and the back of the boiler will be higher than the front.
The EK1 Frontier is pitched 1/4" and the EK2 Frontier is pitched 7/16".
PIPING
All piping and accessory connections should follow good
practice using approved joint sealants.
Figure 2C indicates a typical flow schematic for boiler water
feeding multiple zones. Each system will vary according to
job location.
Supply and return connections are 1”NPT on the EK1 and 1-
1/4”NPT on the EK2.
Call Energy Kinetics to obtain piping and wiring instructions
for alternate applications, such as hydronic heating, radiant
heating, domestic hot water, swimming pool heating, multiple
boilers, injection loops, etc.
Figures 2A and 2B indicate general system piping
arrangement and options. Piping of individual systems may
vary from Figures.
ZONE CONTROL
ZONE CONTROL BY VALVE: The SYSTEM 2000 Boiler is
designed to provide multi-zone control of the heating system and
optionally can supply domestic hot water. Energy Kinetics
recommends and supplies two wire, full port, 24-volt zone valves for
control of each heating zone. A system with a single heating zone
still requires a zone valve to provide control for preheat of unit and
to maintain minimum temperature during operation.
ZONE CONTROL BY CIRCULATOR: Zone control by circulators
requires a flow valve, circulator and 24-volt relay (Multi relay kits or
Individual relays such as a RIB relay available from Energy Kinetics)
for each zone. The main circulator and boiler bypass line are still used in these cases. NOTICE: An additional tee must
be installed into the supply on the inlet side of the main circulator. This tee is the supply for circulators with returns for
these zones into normal return location. Call Energy Kinetics and request “Zoning with Circulators” diagram.
